I'm a sound contractor for games and I'm currently teaching a one-on-one sound design course via Skype in my spare time. Essentially, I guide my students through all the stages of putting together a great sound demo for showing to potential clients/employers.
Here is an example of the stuff I do
I have made a living exclusively from audio work for the past 17 years, and have worked for game companies like EA, Ubisoft and THQ. You can check my bio and credits at my website

to the course's curriculum, requirements and cost.
